//1.axios前置拦截器：每次通过axios发送请求之前，让所有的请求都携带token
axios.interceptors.request.use(config=>{
  //从localStorage中获取token
  let token =  localStorage.getItem("token");
  //如果有值
  if(token){
    //将token设置到请求头
    config.headers['token']=token;
  }
  return config;
},error => {
  Promise.reject(error);
})

//2.axios后置拦截器：后端处理完axios请求之后，处理响应的数据
axios.interceptors.response.use(res=>{
  if (false === res.data.success && "noLogin" === res.data.msg) {
    localStorage.removeItem("token");
    localStorage.removeItem("logininfo");

    next();
  }else{//访问其他页面 - 判断是否登录过 - logininfo
    let logininfo = JSON.parse(localStorage.getItem('logininfo'));
    if(logininfo){
      next();
    }else{//访问的不是登录页面，页不是注册页面。没有登录
      next({ path: '/login' })
    }
  }
})

//router.afterEach(transition => {
//NProgress.done();
//});

initIndexRouters();
function initIndexRouters(){
  if(!localStorage.menus){

  //防止重复配置路由：5就是main.js中路由的个数 - 如果你的静态路由是6个这里要写成6
  if(router.options.routes.length>5){
    return;
  }
  let menus = localStorage.getItem('menus');
  menus = JSON.parse(menus);
  let tempRouters = [];
  menus.forEach(menu=>{
    let indexRouter = {
      path: '/',
      iconCls: menu.icon,
      name: menu.name,
      component: resolve => require(['@/views/Home'], resolve),
      children: []
    }
    menu.children.forEach(cMenu=>{
      let cr = {
        path: cMenu.url,
        name: cMenu.name,
        component: resolve => require(['@/views/'+cMenu.component], resolve)
      }
      indexRouter.children.push(cr)
    })
    tempRouters.push(indexRouter)
    router.options.routes.push(indexRouter)
  })
  //动态路由配置
  router.addRoutes(tempRouters);
